Reka Releases Rho-1: A 19B Omni-Reasoning Model for Video Understanding, Generation, and Robotics

Reka has released Rho-1, a 19 billion parameter omni-reasoning model capable of understanding and generating video while also outputting robot action sequences within a single unified architecture. This positions Rho-1 as one of the few models that spans video comprehension, video generation, and embodied action prediction in a single system, without requiring separate specialized models for each modality. For developers working on robotics, video AI, or multimodal agents, Rho-1 represents a meaningful architectural advance in unifying perception and action under one model. The 19B parameter scale keeps the model accessible for research and experimentation without requiring hyperscale infrastructure. Reka's release adds a credible new entry to the competitive omni-model space alongside models from Google and OpenAI.
